---help---
|
|
X.25 is a set of standardized network protocols, similar in scope to
|
|
frame relay; the one physical line from your box to the X.25 network
|
|
entry point can carry several logical point-to-point connections
|
|
(called "virtual circuits") to other computers connected to the X.25
|
|
network. Governments, banks, and other organizations tend to use it
|
|
to connect to each other or to form Wide Area Networks (WANs). Many
|
|
countries have public X.25 networks. X.25 consists of two
|
|
protocols: the higher level Packet Layer Protocol (PLP) (say Y here
|
|
if you want that) and the lower level data link layer protocol LAPB
|
|
(say Y to "LAPB Data Link Driver" below if you want that).
|
|
|
|
You can read more about X.25 at <http://www.sangoma.com/tutorials/x25/> and
|
|
<http://docwiki.cisco.com/wiki/X.25>.
|
|
Information about X.25 for Linux is contained in the files
|
|
<file:Documentation/networking/x25.txt> and
|
|
<file:Documentation/networking/x25-iface.txt>.
|
|
|
|
One connects to an X.25 network either with a dedicated network card
|
|
using the X.21 protocol (not yet supported by Linux) or one can do
|
|
X.25 over a standard telephone line using an ordinary modem (say Y
|
|
to "X.25 async driver" below) or over Ethernet using an ordinary
|
|
Ethernet card and the LAPB over Ethernet (say Y to "LAPB Data Link
|
|
Driver" and "LAPB over Ethernet driver" below).
|
|
|
|
To compile this driver as a module, choose M here: the module
|
|
will be called x25. If unsure, say N.
